A multi-time-point modality-agnostic patch-based method for lesion filling in multiple sclerosis
No full textMultiple sclerosis lesions influence the process of image analysis, leading to tissue segmentation problems and biased morphometric estimates. Existing techniques try to reduce this bias by filling all lesions as normal-appearing white matter on T1-weighted images, considering each time-point separately. However, due to lesion segmentation errors and the presence of structures adjacent to the lesions, such as the ventricles and deep grey matter nuclei, filling all lesions with white matter-like intensities introduces errors and artefacts. In this paper, we present a novel lesion filling strategy inspired by in-painting techniques used in computer graphics applications for image completion. The proposed technique uses a five-dimensional (5D), patch-based (multi-modality and multi-time-point), Non-Local Means algorithm that fills lesions with the most plausible texture. We demonstrate that this strategy introduces less bias, fewer artefacts and spurious edges than the current, publicly available techniques. The proposed method is modality-agnostic and can be applied to multiple time-points simultaneously. In addition, it preserves anatomical structures and signal-to-noise characteristics even when the lesions are neighbouring grey matter or cerebrospinal fluid, and avoids excess of blurring or rasterisation due to the choice of the segmentation plane, shape of the lesions, and their size and/or location

Entre dos mundos: Jaime Ferran
No full textJaime Ferran, poet of the Generation of 50 and author of the Anthology Part, bringing together poets of the so-called School of Barcelona, is an author semidesconocido reader to the general public and even to most specialists poetry 50. a number of vital and literary circumstances, largely explain this almost forgotten where he has been the work of the poet of Cervera. Notable among them are the fact of having written most of his work outside of Spain. His professional life in Syracuse, USA, led him to build a work outside the concerns of their classmates and also regardless of the prevailing poetic fashions in Spain especially during the decades of the sixties and seventies. In this biographical fact we should add other life and literary adventures that have made Jaime Ferran a kind of outsider.Jaime Ferran, poeta de la Generación de los 50 y autor de la Antología Parcial, que reúne a los poetas de la llamada Escuela de Barcelona, es un autor semidesconocido para el gran público lector e, incluso, para la mayoría de los especialistas en la poesía de los 50. Hay una serie de circunstancias vitales y literarias que, en buena parte, explican este casi olvido en el que ha quedado la obra del poeta de Cervera. Entre ellas cabe destacar el hecho de haber escrito casi toda su obra fuera de España. Su vida profesional en Syracuse, EE.UU, lo llevó a construir una obra al margen de las inquietudes de sus compañeros de promoción y al margen también de las modas poéticas imperantes en España durante, sobre todo, las décadas de los sesenta y los setenta. A este hecho biográfico habría que añadir otras peripecias vitales y literarias que han hecho de Jaime Ferran una especie de outsider
